Abstract: The invention relates to a method for controlling a wind turbine system, more particular for a controlled sliding strategy to lower loads on the yaw system by controlling mechanical brakes and motor brakes in the yaw drive actuators. 5 When the yaw system (300) being in the non-yawing operational state, and the mechanical brake(s) (400) being in an engaged state, and the yaw controller (308) determines or receives a signal indicative of a yaw moment, and if the signal indicative of a yaw moment is above a signal threshold, then the yaw controller (308) sends a braking signal to the yaw drive actuators to enter the 10 motors into the brake state to apply a braking torque.
